To a'ZZ rwwm 'it may concern.' BeA it knownthat I, Oni/mn j MEW, e. citizen ofthe United States, residing at Peoria.,y in the county of Peoria and State i of Illinois, haveinventedfcertain new and .construction 'w ierebyf the rim may useful Improvements inkollapsible Wheel- Rims,of which" he following is ,a spcificaflhisin ention relates to animproved'demountable .vvheeLrim"for4 motor vehicles 'and has as ritnaryfobjeet toprovide a lapsed soI thatiatire may be easi1y"placed upon orlremvedfrom the run. v

The in Iention has as avurtherobject. to

4. provide 4 9, v rjmj embodying coacting hinged rim sectiolis'whieh may be swung inwardly for collapsing'fthe rim .and-to alsoprovide. an improved hinge inemberjfor connecting the sections at ythe meeting ends thereof.

A. further objectoflthe invention 1s toV .provide a rim wherein'the hinge member will be formed withjstop arms arranged to projectthrogh thel'rini' to engage the lnner side thereof for limiting the hinged run sections 4in their*outwardimovement to active position.

And'the Ainvention has as `ajstill further'.

objeotto provide a crmstructionv wherein the said stop arms will be equlpped with studs for engagement withthe hinged ri msections to hold the meeting ends thereof against relative transverse movement as well as to rigidly "connect, the said sections and thus relieve lthe strain upon the hmge. lugs ano.

Fig.r4f -is a transverse sectional view" on the line 4-4 of Fig; 3, showing, on an enlarged scale, the manner in which the hin e member is swingingly connected With t e rlm sections. i w Y Fig. 5 is a plan view with the hingmember removed, this view particularly show ing the seat formed in the bottom of the rim at the meeting'ends of the rim sections for1receiving the body of the hinge member com necting the said sections.

Fig. 6 is a fragmentary sectional view showing a modilied lform of hinge between therim sections and the bod of the rim, and F1g. 7 is a fragmentary' p an view of such modified form of hinge.

.Referring more particularly to the drawings it will be noted that my improved rim is of the channel type and includes a split resilient rim body 10 formed of swingingly connected members. Swingingly connected 'J5 tothe free ends of the rim body are reactingv rim sections 11. The outer ends of therim sections are joined to the ends ofthe rim body by butt hinges 12 and arranged to overlie the joints at the said hinges are lap.

said plates are adapted to project within the outer ends of 'the hinged rim sections for thus presenting a smooth surface to a tire et the joints octwcen'the hinged rim sec yhinges l2 while the inner extremities ofthe 35 tions and the body. Secured to the inner extremities of thesaid plates are laterally projectingstuds 14 adapted :for engagement l insuitable openings in the inner extremities of the rim sections to. provide Va rigid connection betweenthe rim .body and thes/aid 95 sections'.` Moreover, *the stride will brac'f" the outerV ends oi the rim-sections and the .adjacent ends of the rimbody against relative 'transverse movement. .A hinge 1 2 similar to the hinges 1 2 is employed to' conneet the members of the rim cated With the hinge 12 similar to the plates 13.

At theineeting ends of the hinged rim sections 11,- the bottom wall of the rimis,

body and assois a' lap plate '13 as particularly shown in Fig. 5, pressed out to provideasocket or seat 15-at the ends of whichv are formed transversely extending slots 16. Adjacent the ends of these slots the rim sections are further provided with i U5' ingly-connecting the meeting ends ofthe rim openin 17 defining pivot webs 18 between the said openings and the slots. Swing'- Vsections is a hinge member including a body or hinge plate 19 normally received within the socket 15 to lie Hush with the bottom -wall-of' the rim. This plate is formed at its ends with airs of hinge lugs 20 bent to project'throug -the extremities of the slots 16 and extending at their free extremities into the o enings 17 to consequently embraceithe pivot webs 18 for svangingly connectinsaid plate with the rim sections.

' Exten ing from the ends of the plate 19 bemember is a locking key 24 adapted to pro-Y tween the pairs of lugs 20 and projecting through the slots 16 are longitudinally reducedstop arms 21. These stop arms are,

as 'particularly shown in Fig. 35 offset adjacent their inner extremities to lie Hat against the inner faces of the hinged rinr sections at their inner ends and are'formed at ytheir. outer extremities with laterally yenlarged head's'22. These heads provide an increased bearing area for the said arms at their outer ends and are equipped with outwardly'projecting studs 23 adapted forengagementin suitable openings in the bot- Atom walls of the rim sections. be seen that these studs '23 will 'coact with the rim sections to provide a rigid eonnec- It will thus tion between the inner ends thereofa'nd con sequently relieve the strain upon: the 'hinge lugs 2O of 4thehinge member as well as the strain upon the hinge webs4 18 ofthe' rim' sections. At the same time these lugs will also coact'wlth 'the rim sections for bracing the inner ends thereof against relative transverse movement.

l Swiveled upon the plate 19 oi the hinge ject through a suitable opening 25 'at the -meeting ends of the rim sections 'and provided with an oblong head 2G rotatable to en age beneath the said sections for thus loiing the sections against inward Inovement. Thehinged rim sections willthus be held rigidly in active position to complete the contour ofthe rim and coa'ct with the rim body for supporting a' tire. As will now be Seen lthekey v21 may be released when, by

illustrated a slight modification the outer ends of pressing inwardly upon the meeting ends of the hinged rim sections, thesaid sections may be, swung inwardly to inactive position for collapsing the rim.- Upon the initial movement of the meeting ends of the rim.` y

sections, the outer endsof the said sections4 will, of course, move out of engagement with Y the studs 14 of the lap plates 13, while the studs 23 of the arms21 ofthe hinge memi ber connecting the said sections will move out of engagement with the sections at their inner extremities so that the initial swinging of the sections at their meeting ends will be unhanipered. 'After the hinged rim sections have been swungto inactive position, the

.members 'of the rim body maybe pivoted inwardly upon each other at the'hinge 12 so that a tire may, as will be Awell understood, be readilyremoved from the rim. l

For mounting a tire upon the rim the rim is, of cou-rse, first collapsed and the'tire initially fitted inV position thereon.. The' ineinbers ofthe rim body are tlienpivoted outwardly to fit against the tire when the meetingen'ds of the-rim sections are swung outwardly to active position as shown in Figs. 1 and 3 of the drawings, contour of the rim. Inthis connection par ticular attention is directed tothe fact that' when the inner ends of the -rim sections are so. sw ung outwardly the arms 21 will engage.

for completing the the inner ifa'ces of the saidrim 'sections at their 'meeting ends for'limiting the saidsec-4 tions intheir outward movement.: Outward displacement' of the meeting ends of the rim' sections is thus positively prevented while, as

previously explained, the said arms will oo'- operate withtlie rim sections for bracing the said sections with respect'to each other .as

In Figs; 6 and 7 ofthe drawings have` which relates more particularly to fthe.' hinge construction, between theoutei ends of the rim sections andthe endsv this modification the bottom wallbf the rim Ybody is, at its ends, provided withextensions 27 bent beneath, the'rim body and secured by suitable fastening sions are' cutaway to form hinge lugs 29.
